 Every time, the application gets a segment of sequence numbers at the configured step. It updates the database at the same time to persist the maximum value of the current sequence that has been allocated. The processing and allocation of sequence numbers are completed in the application's memory. After a segment of sequence numbers is used up, the application gets a new segment of sequence numbers, which effectively alleviates the pressure on the database write. In practice, you can also adjust the step to control the frequency of database updates.
